CHARLES M. MANLY, OF BROOKLYN, NEW YORK.

INTERNALCOMBUSTION ENGINE.

Application filed March 13, 1911.

To all whom it may concem:

Be it known that I, CHARLES M. MANLY, a citizen of the United States,residing at Brooklyn, county of Kings, and State of New York,-haveinvented certain new and useful Improvements in Internal-CombustionEngines, of which thefollowing 1s a specification.

My invention relates to internal combustion engines and moreparticularlyto that type of engine wherein the fuel 15 1n ected into thecylinder in the liquid-state.

The object of this invention is to provide means for vaporizing the fuelso introduced which is simple in construction andeflicient in operation.

With this and other objects in view my invention comprises the novelconstruction and arrangement of parts hereinafter described and moreparticularly pointed out in the claims.

In the drawingsFigure 1 is a section of a portion of the cylinder of anengine of the type referred to provided with this ll'lVeIb tion; Fig. 2is a perspective of one of the vaporizer plates; F g. 3 is a side viewpartly in section of a modified form; and, Fig. 4 is a perspective ofone of the plates thereof.

Referringto the drawings wherein like reference characters indicate likeparts throughout the several figures, 1 indicates a portion of the topof the cylinder of an engine of the type referred to. Formed integr-alwith the cylinder is a vaporizing chamber 2 having a top plate 3- boltedthereto. Depending from this plate is a bolt or rod 4 and attached tothe rod is a plurality of spaced plates of a size to have a slightclearance between their perimeters and the Wall of the chamber. In Fig.1 I have shown the plates to be seven in number and of these the bottomplate 5 is solid and at right angles to the rod 4 while the upper plates6 are provided with a plurality of perforations 13 and are inclinedrelatively to each other and to the supporting rod 4, thereby formingdiverging openings or spaces be-' tween the plates, extending from sideto side of the chamber 2. A convenient means of attachin the plates tothe rod is shown in the drawing and comprises clamping nuts 7 on the rodabove and below the plates, the upper plates being provided withcentral, integral hubs or bosses 8, the bores and faces of the bossesbeing at the proper angle Specification of Letters Patent.

to the faces of the plates to maintain the plates in the desiredrelative positions.

Set in the Wall of the chamber 2 in such positions as to be opposite thewidest spaces between the plates are several nozzles 9, to which areconnected pipes 10 through which the liquid fuel is intermittentlyinjected by a suitable pump mechanism, not shown. Also set in the sideof the chamber 2 is the usual spark plug 11 for igniting the charge andmounted in the top plate 3 is a priming cup 12 of the usualconstruction.

The operation of the device will now be described. The engine is primedby introducing into the cylinder through the priming cup 12 a smallquantity of a volatile hydrocarbon, as gasolene, before the liquid fuel,usually kerosene, is injected through the nozzles 9. The engine is thenstarted in the usual manner. The heat developed by the explosion of thegasolene raises the temperature of the plates to a point sufficient tovaporize the kerosene injected through the nozzles 9 and thereafter thesuccessive explosions maintain the temperature of the platessufficiently high to vaporize each succeeding charge of fuel. I havefound that the vaporization of the fuel is materially aided by theperforations in the plates and by arranging certain of the plates sothat they present inelinedsurfaces opposite the bores of the nozzles 9.The perforations afford a larger radiating surface than can be obtainedby solid plates in the limited space of the vaporizing chamber besidesaflording very hot passages through which the gasified vapor passes andinsures that any fuel in the liquid state will be vaporized by drippingthrough them and the sharp edges of the perforations maintain a highertemperature than the body of the plates, and in addition, the sharpedges of the perforations serve to mechanically break up or atomize theliquid discharged against the plates through the nozzles. This latterresult is better obtained by the inclined surfaces of the plates whichpresents the edges of the perforations in line of the injected fuel.This arrangement of the plates also prevents the fuel passing betweenthe plates to the opposite side of the cylinder in a liquid state. Thebottom plate is formed solid to catch and retain until it vaporizes, anyliquid fuel that may drip through the upper plates.

In Figs. 3 and 4 I have shown a modified form of my improved vaporizer.In this form the perforated plates 6', instead of being of uniformthickness and inclined relatively to each other, each have one faceinclined relatively to the other face and to the bore for the rod. Theseplatesare preferably arranged so that every other plate is reversed,that is, assuming one plate .to have its inclined surface the uppersurface, the next plate is arranged with its inclined surface downward,and so on through the entire stack. The plates having their inclinedsurfaces adjacent are preferably arranged with their thick edges on thesame side of the chamber thereby forming a diverging space into whichthe liquid fuel may be injected. The next pair of plates may have theirthick edges adjacent a different portion of the chamber wall touniformly distribute the metal throughout the chamber.

In Fig. 1 of the drawing I have shown the vaporizer as consisting ofseven plates and the chamber as provided with three nozzles foradmitting the fuel while in Fig. 3 I have shown the vaporizer asconsisting of eight plates and the chamber as having but one nozzle. Itis to be understood, however, that with either form of vaporizer anydesired number of plates and nozzles may be provided, since in largesize engines where a considerable quantity of fuel is deliver-ed at eachcharge it is desirable to have several nozzles so that the fuel will bedelivered in fine streams and more evenly distributed over the heatedplates.

I claim- 1. In an explosive engine, the combination with a cylinder, ofa plurality of plates mounted therein, certain of said plates beingperforated and arranged in juxtaposition with their adjacent surfacesinclined with respect to each other, thereby forming a plurality ofV-shaped spaces between said plates, and a plurality of nozzles arrangedin said cylinder adjacent the widest portions of said ,V-shaped spaces.

2. A vaporizerfor explosive engines comprising a rod depending from thehead of said engine, a plurality of plates carried by said rod, certainof said plates being perforated and having their surfaces in clined withrespect to the adjacent surfaces toward different sides of saidcylinder, and

a plurality of nozzles arranged in said cylinder adjacent the widestportions of said V-shaped spaces whereby liquid fuel may be injectedbetween said plates.

4. In an explosive engine, the combination with a cylinder of aplurality of plates supported in said cylinder adjacent the top thereofand arranged one upon the other, said plates having their adjacent facesinclined oppositely to each other and provided with perforations topermit the passage of liquid and vapor from the top plate through allthe plates except the bottom plate.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses, this llth day of March, 1911.
